trans-(N(CH3)4)2[Ni(II)(H2O)4(S2O3)2], are isomorphous and contain the novel anions trans-[M(II)(H2O)4(S2O3)2]2- [M=Co(II) and Ni(II)]. The anions are centrosymmetric with the metals in octahedral environments; [Co(II)–S, 2.488(2); Co(II)–O, 2.104(3), 2.120(3); Ni(II)–S, 2.452(1); Ni(II)–O, 2.080(2), 2.100(2) Å]. D, trans-Na[Co(III)(en)2(S2O3)2], and E, trans-NH4[Co(III)(en)2(S2O3)2]·2H2O contain the trans-[Co(III)(en)2(S2O3)2]1−
已经确定了具有单齿硫代硫酸根-S连接的五个单体配合物的晶体结构。A(NH 4)6 [Co(II)(S 2 O 3)4 ]·H 2 O包含一种新型的[Co(II)(S 2 O 3)4 ] 6-阴离子,其中钴具有一个扭曲的四面体配位环境,并键合到四个离散的硫代硫酸盐配体:(Co–S,2.330(3)–2.351(4)Å)。B,反式-(N(CH 3)4)2 [Co(II)(H 2 O)4(S 2 O 3)2 ]和C,反式(N(CH 3)4)2 [Ni(II)(H 2 O)4(S 2 O 3)2 ]是同构的,并且包含新颖的阴离子反式- [M(II)(H 2 O)4(S 2 O 3)2 ] 2-[M = Co(II)和Ni(II)]。在八面体环境中,阴离子与金属是中心对称的。[Co(II)–S,2.488(2);Co(II)–O,2.104(3),2.120(3);Ni(II)–S,2.452(1);Ni(II)–O,2
